In this Tuesday, Nov. 29, 2016 photo, U.S. Army veteran Roosevelt Smith III, center, enjoys time with other veterans and volunteers in an evening of community dance designed for veterans and families who are affected by PTSD, in Louisville, Ky. The environment is built for maximum comfort: lights are kept low for dancers with traumatic brain injuries, the music is cheery without heavy beats and the location is not advertised to provide anxious visitors a sense of security and privacy. The group sessions are kept small, usually less than 30 people (AP Photo/ David Stephenson)
